' This invention relates to slide buckles used for adjusting the length'of looped straps,

webbing, or the like, threaded therein without penetrating the material, and especially to that class of slide buckles of which the frame and the intermediate bar structure are made from a single piece of wire, and the objects of the invention are to provide an in-- destructible slide buckle; and to provide a slide buckle of the pair of loops type, connected at one side and free at the opposite side, with a securing member adapted to relatively secure the loops at their free side. With these and other objects in View, as may become apparent from the within disclosures, the invention consists not only of the particu-. lar form herein pointed out and'illustrated in the drawings, but readily admits of certain modifications within the scope of what hereinafter may be claimed. r

The character of the invention may be best understood by the reference to one illustrative device embodying the invention and illustrated by the accompanying drawings in V which the Figure 1 is an upright elevation of the device; the Figure 2 is a cross-section on the line 22 in the previous figure; and the Figure 3 is a fragmentary front elevation of one of the side structures ofthe device and illustrating a securing member in a relative position therewith to be folded around two right angled portions thereof.

The device about to be described is an improvement upon a slide buckle structure well known in the art and which is made from a single piece of wire bent to'provide a pair of loops integrally connected at one side and free at the opposite side. Such a structure is.

easily distorted or destroyed by means of pulling apart the loops at their free side. The applicant in a previous application filed December 13, 1929, Serial Number 413,864, therein disclosed a slide buckle structure of the pair of loops type of which the engaging metals of the free side of the loops are united SLIDE BUCKLE in permanent intimate unionas are also the engaging metals of the wire extremities and a side structure, the securing means therein including by inference the extraneous elegaging metals. The novelty herein disclosed however resides in a securing means provided ment of heat necessary to amalgamate the enportions adapted to be folded around adjacent 56 parts of Wire structure that are at an angle,

one to the other. i

As illustrated,the device is chieflymade of wire a middle portion of which is bent toform the pair of loops land 2 in a common kin plane, each of said loops having an open and unobstructed interior area, and both of said loops being" integrally connected by means of the side structure 3, but free atthe opposite side, the Wire ends 4 and 5 extending integrally from the free side of the loops '1 and 2, across the slide buckle and in planes parallel one to the other but perpendicular to the free sides of the loops 1 and 2, the wire extremities 6 and 7 engaging the side structure 3 that the wire'ends 4 and 5 may thus complete the loops 1 and 2 which together provide the upper horizontal bar 8, the lower horizontal bar 9, the connected side struc- 11, the wire'en'ds 4 ,and 5 together providing the slide buckle with a horizontal intermediate barstructure. ber 12 may be made in'any convenient form The sheet-metal meme and 12--E (illustrated by the Figure 3) around a part of each of theside structure portions 10 and 11 or, as used uponthe opposite side of the slide buckle, around the side structure 3, while the other portion of the securing member is adapted to be folded along the dotted lines 12F, 12Gr, 12H, and 12I (also illustrated by the Figure 8) around adjacent parts of the wire ends 4 and 5, or the extremities 6 and 7 as illustrated by the Figures 1 and 2, the loops 1 and 2 thus being securely connected at their otherwise 'I'ree side by means or" a securing member 12, and the extremities 6 and 7 being securingly connected with the side structure 3 also by means of a securing member 12. The slide buckle, thus having its parts relatively secured in the manner described, thereby becomes practically indestructible by Wanton manipulation or by use.

I claim 2- 1. A slide buckle comprising a piece of wire of which a middle portion is bent to form in a common plane a pair of loops integrally connected at one side and free at the opposite side, each of the wire end portions forming a part of one of said loops and both of the said wire end portions extending from the said free side in planes parallel one to the other and perpendicular to the free sides of the loops to engage their extremities with the connected side, a sheet-metal securing member securing the loops one to the other at the said free side, and a similar securing member also provided by the loops to secure the engaging extremities of the Wire to the said integrally connected side.

2. A slide buckle comprisinga piece of wire of which a middle portion is bent to form in a common plane a pair of loops integrally connected at one side structure and free at the opposite side structure, each of the wire end portions forming a part of one of said loops and both of said wire end portions extending from the said free side in planes parallel one to the other and perpendicular to the free sides of the loops to engage their extremities with the said connected side, means provided by both loops to relatively secure the loops one to the other at the said free side, and similar means also provided by the loops to secure the engaging wire extremities to the said integrally connected side, each of said securing means comprising a sheet-metal member of which a portion is adapted to be folded around a side structure and an integral portion of said member being adapted to be folded around adjacent structure which is at right angles to said side structure.

3. A slide buckle comprising a piece of wire of which a middle portion is bent to form in a common plane a pair of loops, each loop having an open and unobstructed interior area, and both loops being integrally connected at one side and free at the opposite side permitting the separation'of one loop from theother along said plane, each JOHN H.
